Abstract:

A monitoring data reporting system is designed for shield machines so that the tunneling management personnel can analyze the historical data of the shield machines conveniently. In the paper, the monitoring data reporting system is studied in terms of overall structure of the system, historical data analysis and key technology application. For the sake of the monitoring data reporting system mentioned, automatic data selection, automatic data filtering, automatic data statistics, automatic data calculation and automatic ringbased reporting file generation are realized. The data monitoring system has been applied on CREC shields, which demonstrates that the contractor and the client can know the conditions of the tunneling and the shields conveniently by means of the monitoring data reporting system and the management cost has been reduced dramatically. 

Key words: shield monitoring data, data analysis, report system, plugin, SQLite database
